This is one of the
two main stationary defenses the rebels used to hold of the Imperial
forces during the Battle of Hoth in The Empire Strikes Back.
I used both a webbed and non-webbed dark grey 6x6 radar dish on
this, as the real cannon is covered but does have the basic pattern
of the webbed radar dish in it. The only piece in this that's not
available in dark grey is the 1x2 hinge brick top, which I had to
substitute black for (it doesn't take away from it any, in my opinion).
It has an oval-shaped black base with an energy hookup. It's fifty-seven
pieces and measures about tenstuds long by six wide and nine tall.
The last two images show my Rebel Commander remotely controlling
the cannon.
